| I have a 1 yr. old Golden Retreiver. We got the underground fencing, but it seems we always have a problem with it. Ran over cord, didn't work. Struck by lightening, didn't work. Had a dumpster in yard, didn't work. Latest is that it got very cold here for a long time this winter and it hasn't worked since. The dog runs off the second he is let out, so we've been chaining him up - then he bark |
